VEGA VEGASON 71 - 1 … 75 - 1 - Manual (Page 29)

Measurement, Relay output
71 - 1 … 75 - 1 29
Mode (Module 1, relay output 1) continuation
Mode 0 - 44 = 1
two-point level switch
switching command 1 via
switching command 2
corresponds to function B
(protection against dry
running of pumps)
Switching command 1 and 2 (Module 1, relay output 1) MODE 0 - 45 and 0 - 46
Mode 0 - 43 defines the measurement units
coordinated to the relay output.
Mode 0-44 determines the function of the relay
output.
Mode 0-45 = switching command 1 corresponds
to switch on (on)
Mode 0-46 = switching command 2 corresponds
to switch off (off)
With the operating sequence of the switching
commands, the A- or B-function i.e. overfill protec-
tion or protection against dry running of pumps is
determined.
See diagram page 28 and 29.
The min.-
∆
for the switching commands is 10 cm or
0,5 %.
Programming example for relay output 1 ............... - coordination to channel1 with units in %
- mode 1
- two-point level switch in function A
(see page 28)
Coordination .............................................................. • select mode 0 - 43 in MODEFIELD
• program figure 2 in PARAMETER FIELD
• then store with STO-button
Mode (two-point level switch) .................................... • select mode 0 - 44 in MODEFIELD
• program figure1 in PARAMETER FIELD
• then store with STO-button
Switching command 1 (on) ...................................... • select mode 0 - 45 in MODEFIELD
• program 025.0 % in PARAMETER FIELD
• then store with STO-button
Switching command 2 (off) ....................................... • select mode 0 - 46 in MODEFIELD
• program 050.0 % in PARAMETER FIELD
• then store with STO-button
Same function and procedure
for module 1, relay output 2
and module 2, relay output 3 and 4 however
with respective modes, see page 28.
